PRODUCTS COMPANY, OF BARBEBTON, OHIO, .A CORPORATION OF OHIO PROTECTIVE COVER FOR IGNITION DISTRIBUTORS Application filed June 28,

This invention relates to soft-rubber protective covers adaptedto be fitted to ignition distributors for automobiles, etc,, for the principal purpose of excluding water from the places where the high-tension wires enter the distributor cover, and'thus to avoid shortcircuiting of the wires. J

As heretofore constructed, these protective devices have generally been made with long skirts so that the device encloses the entire upper portion of the distributor at the top and sides, but in some cases the covers are made as a mere cap with a short skirt. As the distributors come in various sizes, the protective cover has to be furnished in different sizes to fit, or else will have either too loose or too tight a fit. The object of my present invention is to provide a protective cover which may be made in fewer sizes, or only one size, which will fit with sufiicient tightness on different sizes of distributors, said cover having means for more or less closing the space between its lower edge and the distributor. Of the accompanying drawings, Fig. 1 is a side elevation of a distributor provided with my IIIIPIOVGdIOIIIl of protective cover which is shown partly in section. Fig. 2 is a plan view of the protective cover partly in section.

' In the drawings, 10 is an ignition distributor comprising a fixed lower body 11 and a detachable cap member 12 secured thereto by latches 13 and formed with the usual tubular pro ect1ons 14 on its upper side through which the insulated high-tension wires 15 enter the distributor. I

16 is my improved protective cover made of soft, vulcanized rubber in the form of a hollow dome or inverted cup molded with tubular projections 17 on its upper side for tight- 1y embracing the wires 15 and excluding the entrance of water from above. This protective cover preferably has a relatively-short 4 skirt portion 18 so that the cover encloses only the upper portion of the distributor, and the lower edge of said skirt is internally molded with a series of segmental, arcuate, flexible rubber lips 19 of sufiicient width to meet the exterior of the cap member 120i the smallest 1929. Serial No. 874,452.

distributor upon which the protective cover is to be used. The ends of these lips 19 are separated by short spaces 20.

In applying the protective cover 16 to a distributor the ends of the disconnected ignition wires 15 are forcedthrough the tubular projections 17 and connected with the terminals inside the distributor, and the cover 16 is forced down over the distributor cap member 12 to the position shown in Fi 1. As it passes downwardly over said mem er 12, the inwardly-projecting flexible lips 19 are bent upwardly 'more or less according to the Width of the space between member 12 and the skirt 18, while their inner edges contact with member 12 and serve not only to resist upward displacement of the cover 16, but also substantially to close the space between said skirt and the distributor, while the spaces 20 between the ends of the lips provide vents affording ventilation which tends to avoid the condensation of moisture upon the thus-enclosed portions of the distributor casing and upon the inner surface of cover 16.

" While I have shown my invention in a pre- 7 ferred form, it will be understood that the embodiment may be more or less varied without departing from the scope of said invention as defined in the claims.

I claim:

1. A soft-rubber protective cover for ignition distributors, said cover comprising a cupshaped body formed with one or more apertures in its end wall for the passage of igni tion wires and having a skirt provided with a flexible, inwardly-projecting structure for engaging the side of the distributor.

2. A cup-shaped, soft-rubber protective cover for ignition distributors, said cover having a perforated end wall and a skirt formed with an inwardly-projecting, flexible, circumferential lip structure.

3. A cup-shaped, soft-rubber protective cover for ignition distributors, said cover having a perforated end wall and a skirt integrally formed with a circumferential series of inwardly-projecting, flexible, arcuate lips separated by relatively-short spaces.
